I'm also one of the guys strongly attracted by this package. It seems
to provide elegant interface for problems that requires elaborate
solvers. I feel that set-cover will grow to one of a swiss-army-knife
tool like SMT solver DSLs. I have several application problems in my
idea list that can be reduced to set cover problems.
I've been testing this set-cover for a while, however, me too am
finding it hard to understand the library. Although the coherent
choices of names and types makes great clues, additional documentation
in natural language might help in better understanding.
I wish to see some articles of set-cover API and examples, when your
